Four main crude polysaccharide fractions, which represented the complete polymeric carbohydrate pool, were isolated by sequential extraction from Digitalis purpurea leaves. These crude fractions were fractionated further by ion exchange and gel permeation chromatography in order to obtain homogenous polysaccharide fractions. The following polymers were identified: the water soluble reserve polysaccharides were mainly composed of neutral and acidic arabinogalactans, neutral and acidic glucomannans and starch. Pectic material from a sodium carbonate extract was identified as rhamnogalacturonan. Hemicellulosic cell wall polysaccharides consisted of a neutral, tow substituted arabinoxyloglucan and several acidic xylans. Hemicellulosic polymers associated with cellulose were shown to be highly branched xyloglucans. Extracellular polysaccharides from Digitalis lanata suspension-cultured cells were fractionated and arabinoxyloglucans, as well as neutral and acidic arabinogalactans were identified. 2,6-Dideoxy sugars, the typical constituents of cardiac glycosides in Digitalis, are not part of the polysaccharide pool of both systems investigated.
